UNITED STATES PATENT OFFICE.

BLOWING MACHINE FOR THE MANUFACTURE OF HATS.

Application filed March 4, 1927, Serial No. 172,809, and in Germany March 12, 1926.

This invention relates to a blowing machine for the nninufacture of hats, particularly what are known in the trade as hat hoods.

In blowing machines hitherto used, only one cone is employed in the blowing con1 partme-nt. When it is desired to make hat hoods of different sizes, it is theretore necessary either to keep in readiness blowing machines suited for the. different sizes or to in ert. into a machine suitable for the largest hoods, a correspondingly smaller cone tor the manufacture of smaller hoods, so that the machine is not completely utilized.

It has been found that small hoods can be manufactured also with machines oi the larger dimensions, in such a manner that sevral smaller cones, for instance, three, are accommodated in a single blowing compartment. It has also been found unenpectedly that during the matting or forming, the filaments or fibres introduced became uni'lormly d'stributed among the cones which of course are preferably mounted in a symmetrical manner.

In this way the necessity of keeping ready machines of (litterent sizes for the ditierent sizes of hoods is avoided. The output is substantially increased as compared with that of machines in which the large cone is replaced by a single smaller cone, so that an increase in the number of machines is unnecessary.

Part 01 a blowing machine embodying the invention is diagrammatically illustrated by way of example in the accompanying drawing, in which:-

Figure 1 is a vertical section and Figure 2 a plan, both partly in section.

1 is the usual blowing compartn'ient, the bottom 2 of which is rotatable in the well known manner. In place of the usual single cone rotating with the bottom, in the construction illustrated there are provided three smaller cones 3 which are supported by a perforated plate l. This plate rests on the rotating bottom 2 of the compartment and rotates with the same. It may be secured to the bottom 2 in any suitable manner. The

openings 5 situated under the cones, may be surrounded by araised edge or flange 6 which holds the cones 3 fast. It is not essential, that the individual. cones should be capable of retating about their axes, as even without this rotation, the fibre"; introduced into the compartment in the usual manner, become uniformly distributed among the several cones and settle 011 them.

What we claim is 1. In a blowing machine for the manufacture of bat hoods the combination, with the blowing compartment, 01 a plurality oi perforated forming cones adapted to receive the deposit oi fibrous material introduced into the compartment, said cones being sup ported by and rotating with the bottom ol the compartment.

2. In a blowing machine tor the manufacture of hat hoods the combination, with the blowing compartment, oi? a plurality of perforated tor-min g cones adapted to receive the deposit of fibrous material introduced into the compartment, said cones being supported by a perforated plate resting on and rotating with the bottom of the (JOlllPfiltIilBllt.

3. In a blowing machine tor the manufacture 0t hat hoods the combination with the blowing compartment, of a plurality 0t symmetrically arranged pertoratod forming cones adapted to receive the deposit 0t fibrous material introduced. into the compartment, said cones being supported by and rotating with the bottom of the compartment.

4:. In a blowing machine for the mainline ture of hat hoods, the combination, with the blowing compartment, 01' a plurality of symmetrically arranged perforated forming cones adapted to receive the deposit oi? fibrous material introduced into the compartment, said cones being supported by a perforated plate resting on and rotating with the bottom ot the compartment.

In testimony whereot we have ailixed our signatures.
